A case report of cardiogenic syncope in the adolescent.

open access: yesMedičnì Perspektivi, 2018
The article presents authors’ observation of a clinical case of the girl aged 15 years old with cardiogenic syncope due to sick sinus syndrome, which progressed from normocardia sinus rhythm to pauses of the cardiac rhythm lasting 10.2-second during 3 ...

Transient unexpected improvement of AV conduction: What is the mechanism? [PDF]

open access: yes, 2006
This ECG was recorded from a 93 year old patient with a previously documented third degree AV block and an underlying LBBB. The twelve lead ECG demonstrates sinus bradycardia at a rate of 52 beats per minute, a PR interval of 230 milliseconds, and a ...

Spontaneous Pothole Cardioversion of a Wide Complex Tachycardia

open access: yesJACC: Case Reports, 2020
External mechanical forces, if properly timed and of sufficient energy, have rarely been reported to convert tachyarrhythmias to sinus rhythm. We report a case of a patient with a wide-complex tachycardia that spontaneously converted to sinus rhythm ...

Clinical and Procedural Effects of Transitioning to Contact Force Guided Ablation for Atrial Fibrillation. [PDF]

open access: yes, 2019
Background: A major innovation in atrial fibrillation (AF) ablation has been the introduction of contact force (CF) sensing catheters. Objective: To evaluate procedural and clinical effects of transitioning to CF-guided AF ablation.

EFFECTIVENESS OF UNIPOLAR RADIOFREQUENCY SURGICAL ABLATION FOR ATRIAL FIBRILLATION

open access: yesРоссийский кардиологический журнал, 2015
Aim. To verify the effectiveness of surgical ablation for atrial fibrillation by irrigated unipolar radiofrequency, applied to both atria, for the reversal and maintenance of the sinus rhythm in the short and medium term in patients undergoing ...

Comparison of the Relationship Between Inflammatory Markers and Atrial Fibrillation Burden

open access: yesAnatolian Journal of Cardiology, 2023
Background: Atrial fibrillation is a complex disease with irregular ventricular response and tachycardia as a result of irregular and rapid contraction of the atria, with poor cardiovascular outcomes unless treated. Various mechanisms are involved in its

Frequency Analysis of Atrial Fibrillation From the Surface Electrocardiogram [PDF]

open access: yes, 2004
Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice. Neither the natural history of AF nor its response to therapy are sufficiently predictable by clinical and echocardiographic parameters.
